The number of confirmed cases of dengue fever on the Big Island rose to 139, the Department of Health said Monday.
Of the confirmed cases, 122 are Big Island residents and 17 are visitors. Thirty-one of the cases have been children younger than 18. The last onset of illness occurred Nov. 30.
As of Monday, 424 potential cases have been excluded based on test results and/or not meeting case criteria, officials said.
The Department of Health continues to spray and treat areas with high mosquito presence and confirmed cases in South Kona, Hamakua, South Hilo and Puna.
Dengue fever is a viral illness spread through the bite of mosquitoes. The disease, which does not spread from person to person, occurs mainly in tropical Asia, Africa, the Caribbean and the South Pacific. It is most common during the rainy season in areas infested with infected mosquitoes, according to the state DOH. Mosquitoes breed in areas of standing water (such as planters, old tires and pet water bowls).
Symptoms of dengue fever usually start within six days, but can take up to 15 days to appear. They include sudden onset of fever, severe headache, eye, joint, and muscle pain, and a rash that typically appears on the hands, arms, legs and feet within four days of the onset of a fever. These symptoms usually go away within two weeks without medical treatment.
To deter bites, people should take preventative measures like avoiding mosquito-ridden areas. If that is not possible, people should protect themselves with long-sleeve shirts and pants, and bug repellent containing DEET.
